Four points on a graph are (2,3);(-2,3);(-2,-3);(2,-3). if you join if you join the points the shape will be?

A square, I believe. Is that what you got?

rectangle

height from -3 to +3 or 6
width from -2 to + 2 or 4

To determine the shape formed by joining the given points, we can plot them on a graph and observe the pattern. Let's plot the points (2,3), (-2,3), (-2,-3), and (2,-3):

First, draw the x and y axes on a graph. Mark the points (2,3), (-2,3), (-2,-3), and (2,-3) on the graph.

Here is the graph:

```
|
|
|
| (2,3)
________|________
|
|
| (-2,3)
________|________
|
|
| (-2,-3)
________|________
|
|
| (2,-3)
|
```

By joining the points in the given order, we find that they form a rectangle. The sides of the rectangle are parallel to the x and y axes. It can also be observed that the opposite sides of the rectangle have equal lengths.

Therefore, the shape formed by joining the points (2,3), (-2,3), (-2,-3), and (2,-3) is a rectangle.
